Why We Like The Shimano RS785 Hydraulic Disc Brake Caliper
Rim brakes are great, but they have an unfortunate penchant for not working well when wet or when a squirrel runs right out in front of you, so we look to the Shimano RS785 Hydraulic Disc Brake Caliper for reliable, all-condition, fade-free stopping power. It teams up with Shimano's ST-RS685 11-speed components for added performance and features IceTech cooling fins designed to dissipate heat, increase braking response, and keep performance high even during long, steep descents.

Two consecutive calipers w leaking seals
- Familiarity:
- I've put it through the wringer
These would be a great choice, but Shimano has seemed to have lost control of quality here. I have had to replace two of these now because of leaking seals. Completely unacceptable.

Okay calipers.. when they don't leak oil
- Familiarity:
- I've used it several times
I ordered 2 for an Ultegra 8000 build with "post" caliper mounts. Unfortunately, 6 months later one started slow-leaking fluid from the o-ring seal at the port between the caliper halves. It's terrible... pads are consistently glazed and loud. At first I thought my college-athlete son contaminated them, etc., but then after multiple frustrating "what's going on" experiences cleaning the pads with alcohol and sanding and ultimately replacing, I did a bit of research on line... this is well known failure mode with this particular Shimano design. ..kind of disappointing and not their best work. In any event, rather than roll the dice here again I swapped in Hope RX4's (which by the way perform MUCH better). I'm returning the one that is defective to Backcountry as a warranty claim and have the eat the cost on the other. So far the process with Backcountry is a bit confusing - their service is generally excellent but they appear in this case to be set up for returning stuff bought by mistake and not for warranty issues - I'm hoping that this sorts the right way.
